Sennheiser Mx Wireless 1 Twist To Fit Stereo Headphones.

The MX W1 is Sennheiser’s first portable and completely wireless stereo earphone system.  Featuring two separate (left/right) earphones, transmitter and carrying case with integrated charger, the MX W1 offers an uncompressed digital wireless connection and delivers excellent high-fidelity stereo sound, letting you enjoy your favourite music without the hassles of cords.
The transmitter offers the possibility to transmit up to two pairs of MX W1, enabling two people to listen to the same audio player at the same time. The system’s carrying case doubles as a charging station for quick-charging the earphones up to three times while ‘on the move’ — even without access to a power supply system.
